摘要
An activated tridentate-, monoanionic-ligand-based transition metal catalyst in a reduced oxidation state for olefin polymerization is disclosed. Transition metal catalyst precursors for these catalysts have the formulae:in which M is a transition metal from Groups 4-9 in a reduced oxidation state, X is a mono anionic ligand, L is a neutral donor group, E is a neutral donor group from Groups 15 and 16, E' is a monoanionic donor group from Group 15, T is a bridging group, n is 1-3 as needed to balance the charge on M, p is 0-3 and q is 1-2. Olefin polymerization is exemplified.
